not sure what you think your problem with arcane is but i'll share what am doing ^_^
stats/trinkets is very easy, just have to run simc with scaling on and use ingame addon called pawn
2223131 are the talents i use
rotation is very simple: ab x 4 -> dump all am charges -> barrage
repeat until oom then evocate back up
opener:
prepot precast ab @ 1.5sec before pull
ab till 4 charges
mark
rune/apower/presence
spam ab unless capped on missile charges
i use my second rune charge after apower ends making sure to have 2-3 am charges depending on procs
you then go on and burn all your mana
evo up
then u conserve until cooldowns are back up
i like to line up every mark cast with rune which means u have to delay rune 10sec or so after the one u cast during opener
lastly i try to line up apower with rune
anymore questions i'll try to answer
